A runway is a long path for planes to take off and land on an airport.
You might hear the word "runway" mentioned when talking about flights or airports. It's used to describe the way a plane moves, especially at takeoff or landing. Imagine you're watching airplanes arrive at a busy airport - you'll see them taxi down a long path that leads to the end of the runway, where they then lift off into the air. Runways can also be paved with special material to help planes slow down when they land.
A defined, narrow section of land or an artificial structure used for access.
